Movable Bottom Jar

ABSTRACT

The invention comprises a jar or storage container that has a moveable bottom platform with one vertical degree of translation. This will add the ability to move all of the jar&#39;s contents up or down, depending on the position of the bottom platform. For example, if some of the contents within the jar are removed then the moveable bottom can be shifted up to a higher location in order to bring the remaining contents back to the top.

BACKGROUND OF INVENTION

This invention relates to storage devices such as jars, in particular storage devices incorporating a moveable bottom.

1. Background

In the past, the conventional means for storing perishable foods has involved the use of glass, plastic and metal jars and cans which have an inherent oxygen barrier characteristic.

One problem with conventional storage means is that when an item that it is being stored in, such as salsa dip or peanut butter, is running low, it makes it difficult to reach the bottom of the jar (whether you are using a spoon or any other device or food such as a chip) and scoop up the contents. This is not efficient and can cause messes and spills.

2. Description of Prior Art

U.S. Pat. No. 5,092,474 by Leigner and issued on Mar. 3, 1992 is for a “Plastic jar.” It discloses a lightweight plastic jar having outwardly convex front end and back walls, each having a relatively large radius of curvature, and a pair of side walls having relatively large planar portions capable of controlled inward deflection to accommodate decreases in the interior volume of the jar. The jar is configured to facilitate dispensing of product while also providing strength, efficient use of space in packing with like containers, and an attractive appearance.

The need for a device that allows an efficient and easy method to reach items from a bottom of a jar shows that there is still room for improvement in the art.

SUMMARY OF INVENTION

The present invention relates to a jar or storage container that allows an efficient and easy method to reach items from a bottom of ajar by having a movable bottom.

The invention comprises ajar or storage container that has a moveable bottom platform with one vertical degree of translation. This will add the ability to move all of the jar's contents up or down, depending on the position of the bottom platform. For example, if some of the contents within the jar are removed then the moveable bottom can be shifted up to a higher location in order to bring the remaining contents back to the top.

The invention provides the ability to shift the contents of the jar to a higher or lower position within the jar or storage device. If the jar's contents are low, it will be helpful to move the bottom platform of the jar to a higher position so that it will be easier to reach the contents. For example, let us assume that the jar contains a substance such as salsa dip. When the salsa dip is running low, it makes it difficult to reach the bottom of the jar (whether you are using a spoon or any other device) and scoop up the contents. Adding a moveable-bottom platform to the jar, one can shift the platform to a higher position causing the salsa dip to come all the way to the rim of the jar, and thus scoop out the contents without any difficulty.

DETAILED DESCRIPTION

The following description is demonstrative in nature and is not intended to limit the scope of the invention or its application of uses.

There are a number of significant design features and improvements incorporated within the invention.

The word “jar” as used in this description means either a true jar or a container in general, such as a bottle, a can or the like. As shown in FIG. 1, the invention is a jar 1 or container with a moveable bottom 30 which provides the ability to shift the contents 35 of the jar 1 to a higher or lower position within the jar 1. If the jar's contents 35 are low, the user can move the bottom platform 30 of the jar 1 to a higher position so that it will be easier to reach the contents 35 such as salsa or peanut butter. In the current invention, by adding a moveable-bottom platform to the jar 1, one can shift the platform 30 to a higher position causing the salsa dip to come all the way to the rim of the jar 1, and thus scoop out the contents 35 without any difficulty. As with a typical jar or storage container 1, it has an outer wall 10 and an inner wall 20. The movable platform 30 has a diameter that is slightly less than the diameter of the jar's inner wall 20 so that it can move perpendicular to the jar's inner wall 20. The jar 1 can have a flexible lining 70 made of plastic or some other material that can serve to hold the contents 35 within the jar 1 especially if it is a liquid.

The jar 1 or container can have a top such as a typical screw cap top or pop top or any other top that is standard in the industry and not disclosed in great detail here.

FIG. 2 displays ajar 1 with a movable bottom platform 30 that utilizes a spring system. The spring system uses a spring 40 that is located between the bottom of the movable platform 30 and the bottom 60 of the jar 1. FIG. 2 also displays the top, bottom and side views of the movable platform used in the spring system. In the preferred embodiment, the spring tension would be properly balanced as to counter the gravitational force of the contents 35 so that as the contents 35 of the container or jar 1 are removed the movable platform 30 moves up towards the top of the jar 1.

FIG. 3 displays ajar 1 which uses a wedge system moving the movable bottom. In the wedge system the jar 1 has a plurality of wedges 50 on the inner walls 20 of the jar 1. In the preferred embodiment these wedges are located ⅓ and ⅔ up to the side of the jar 1 from the bottom 60. The wedges 50 in the preferred embodiment are made of a flexible material and are angled from the bottom of said wedge 50 to the top of said wedge 50 with the top of said wedge being flat and perpendicular to the jar's inner wall 20 with said wedge 50 being a thin construction. In the preferred embodiment there are four wedges 50 at the ⅓ and the ⅔ jar levels at each of the 90 degree angles from the center. In the preferred embodiment the wedges have the ability to shift position is a motion like a rotation around an axis with the axis being the center of the wedge 50 where the wedge 50 is attached to the inner wall. In the wedge system the movable disk 130 is thinner in the preferred embodiment and made of a flexible but strong material. The wedge system uses the flexible lining 70. The bottom 60 of the jar 1 has a hole 160. The user uses this hole 160 to push the movable disk 130 from the bottom to the next level of hinges 50.

Another embodiment is a tooth shelf system as shown in FIG. 4. In the tooth shelf system the jar 1 has a plurality of teeth 90 on the inner walls 20 of the jar 1. In the preferred embodiment these teeth are located ⅓ and ⅔ up to the side of the jar 1 from the bottom. In the preferred embodiment, there are three teeth 90 at the ⅓ and the ⅔ jar levels at each of the 120 degree angles from the center. In the tooth shelf system the movable platform 180 has a plurality of slots 190, three in the preferred embodiment that correspond with the teeth 90 of the jar 1. It also has a pole 100 that is perpendicular to the movable platform 80 and attached to the center of the movable platform 80 with a balled area 105 at the end of the pole 100. The user uses the balled end 105 of pole 100 to pull the movable platform 80 up and to align the slots 190 with the teeth 90, pull the movable platform 80 past the teeth 90, turn the movable platform 80 so that the movable platform 80 rests on the teeth.

The jar 1 or container can be made of any durable material such as plastic, glass or metal.

Operation

The invention provides the ability to shift the contents 35 of the jar 1 to a higher or lower position within the jar or storage device 1. If the jar's contents 35 are low, it will be helpful to move the bottom platform 30 of the jar 1 to a higher position so that it will be easier to reach the contents 35. The user can shift the platform 30 to a higher position causing the item to come all the way to the rim of the jar 1, and thus reach the contents 35 without any difficulty.
